Use words and drawing to make your sketch as detailed as possible.
All the little details are what make the specimen you are studying distinguishable from others like it. Add labels, questions, and conjectures about what you see. Drawing is a more general term than diagram, so you could say a diagram is a type of drawing.
Generally speaking, a diagram is intended to convey technical information in a clear, visual format. Science Diagrams are copies of technical data that are typically drawn by scientists, from the account of their practical observations and studies, such as biological dissections, chemical experiments, geological analysis or exploration of mechanics.
The ability to imagine things pervades our entire existence. It influences everything we do, think about and create. It leads to elaborate theories, dreams and inventions in any profession from the realms of academia to engineering and the arts.
Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.
In a new study, psychologists Christopher Davoli and Richard Abrams from Washington University have suggested that the imagination may be more effective than we think in helping us reach our goals.

Drawings not only allow you to record an image of the specimen observed but more importantly, they help you to remember the specimen as well as the important features of the specimen.
You will be required to look at a large number of specimens during this course and you are much more likely to remember them if you have to draw each one. Drawing a specimen requires you to pay attention to detail so that you can re-create it on the sheet. While doing this, your brain is recording these same features in such a way that you can recall them if necessary for example in an exam.
Simply observing pictures of specimens in a book or on a computer screen is less effective when it comes to remembering and understanding what you observed. All drawings done for this course must adhere to standard rules of scientific illustration. The following are some guidelines that you are to use when illustrating specimens:.
Do not shade in any area of your drawing. Each label line must be straight and should not overlap with other label lines; all labels must be to one. Annotations are used to give information about the specimen that cannot be seen on the diagram e.
